Description

Technical Field

[0001] This utility model belongs to the field of road maintenance technology, and in particular relates to an asphalt road maintenance spraying device. Background Technology

[0002] Good road conditions improve driver comfort and reduce traffic accidents. There are various types of roads, such as concrete roads, gravel roads, and asphalt roads. Asphalt roads experience wear and tear during use, requiring workers to operate asphalt pavement spraying equipment to maintain them and ensure normal vehicle operation.

[0003] A search revealed a patent document with publication number CN215714443U disclosing an asphalt pavement spraying device for highway maintenance. The device includes a support box, a piston mechanism, a mixing mechanism, and a conveying mechanism. A first motor housing is fixedly connected to the bottom of the support box, and a gearbox is fixedly connected to the top of the support box. The piston mechanism is located inside the support box and includes a first L-shaped shaft, an S-shaped shaft, and a second L-shaped shaft. A first motor is fixedly connected to the bottom of the inner wall of the first motor housing, and the output end of the first motor is fixedly connected to the first L-shaped shaft. The first L-shaped shaft passes through the first motor housing and the support box and extends into the support box. This device relates to the field of highway maintenance technology. Through the operation of the piston mechanism, asphalt in a T-shaped pipe is sprayed from the nozzle to the working area. Alternatively, auxiliary materials in a storage tank can be sprayed from the nozzle to the working area via a second pusher plate, improving work efficiency and avoiding uneven spraying.

[0004] The aforementioned asphalt pavement spraying device for highway maintenance includes a mixing mechanism comprising a second motor housing, which is fixedly connected to the top of a mixing drum. A second motor is fixedly connected to the top of the inner wall of the second motor housing, and a first rotating shaft is fixedly connected to the output end of the second motor. The first rotating shaft passes through the second motor housing and the mixing drum and is rotatably connected to the bottom of the inner wall of the mixing drum. Spiral blades are fixedly connected to the surface of the first rotating shaft inside the mixing drum. When the second motor is started, it rotates and drives the first rotating shaft to rotate, thereby causing the spiral blades to rotate and achieving the purpose of mixing the material. However, it can only mix the maintenance material inside the mixing drum, and it is not convenient to mix the material inside the storage tank. Due to prolonged standing, the maintenance material inside the storage tank will clump together, making it difficult to discharge the maintenance material and affecting the maintenance efficiency of the asphalt pavement. Furthermore, a piston mechanism is provided inside the support box, which includes a first L-shaped shaft, an S-shaped shaft, and a second L-shaped shaft. A first rotating shaft is fixedly connected to the bottom of the inner wall of the first motor housing. A motor is used, with its output end fixedly connected to a first L-shaped shaft. The first L-shaped shaft passes through the first motor housing and the support housing, extending into the support housing. A second L-shaped shaft is rotatably connected to the top of the inner wall of the gearbox. The second L-shaped shaft passes through the gearbox and the support housing, extending into the support housing. One end of the first L-shaped shaft and the second L-shaped shaft located inside the support housing are fixedly connected to both ends of an S-shaped shaft via fixed shafts. Connecting rods are rotatably connected to the surfaces of the two fixed shafts. Connecting blocks are rotatably connected to the other ends of the two connecting rods via through holes. A first push rod and a second push rod are fixedly connected to opposite sides of the two connecting blocks, respectively. The piston mechanism is designed to facilitate material discharge, allowing auxiliary materials in the storage tank to be sprayed out through the second nozzle and asphalt material in the T-shaped pipe to be sprayed out through the first nozzle, avoiding problems of uneven and incomplete spraying. However, the simultaneous discharge of different materials from the storage tank and the T-shaped pipe makes it inconvenient to select different maintenance materials based on the actual road conditions of the asphalt pavement, reducing the applicability and practicality.

[0005] To address these issues, we provide an asphalt pavement maintenance spraying device. Utility Model Content
